World number one Novak Djokovic completed a terrific week by setting two more records in winning the Paris Masters on Sunday.
Djokovic beat defending champion Daniil Medvedev 4-6 6-3 6-3 to win a record sixth Paris title and 37th Masters 1000 crown, moving clear of Rafael Nadal.
Russia's Medvedev, 25, broke Djokovic's serve twice as he took the first set.
But the Serbian, who will end the year as number one for a record seventh time, eased through the final two sets.
Loose games from Medvedev, who denied the Serbian a calendar Grand Slam in September at the US Open, handed Djokovic two crucial breaks in the deciding set.

Elsewhere, Great Britain's Alfie Hewett won the singles title at the season-ending Wheelchair Masters in Orlando.
The 23-year-old beat Gustavo Fernandez of Argentina in three sets in the final, having won the doubles title with Gordon Reid on Saturday.
